Title: Laser amplitude stabilisation or change - uses paramagnetic gas whose absorption line is brought to coincide with laser characteristic
Inventor: WINTERHOFF HORST DIPL PHYS
IPC: G02F1/09
Filed: 1974-06-29
Abstract: The laser amplitude is stabilised or changed by guiding the laser beam through a Zeeman-active, paramagnetic gas whose absorption line is brought into coincidence with the laser line by a magnetic field. The absorption coefficient of the paramagnetic gas is changed via the intensity variation of the magnetic field. Preferably a high gas pressure is used and the desired coincidence may be available even without any magnetic field. In such case the absorption coefficient is adjusted by a magnetic field. The system stabilises a molecule gas laser against amplitude variations caused by the gas composition or by varying spacing of the resonator mirrors. In this way even high frequency amplitude variations can be controlled.

Title: I.C. engine high tension ignition system - control tension is dephased in regard to charging tension to prevent engine running in reverse
Inventor: SASAKI MITUO
IPC: F02P11/02
Filed: 1974-07-04
Abstract: The ignition circuit consists of a magnetic rotor turned by the engine crank shaft to induce a control tension dephased in regard to the charging coils, so that the energy induced in the coils can be stored in the capacitor and discharged through the ignition coil when the engine runs in the correct direction. The control tension is retarded 90 deg. + THETA to the charging tension so that the two tensions partly overlap when the engine runs in reverse to earth the current. The construction of the respective charger stators and the control generator is similar to a conventional generator unit with the exception that the respective rotors are so arranged to each other that the charging generator rotor circumference which runs through the centre of the pole section and the control generator circumference are displaced at an additional angle to the usual 90 deg.
